Hi..air suspensions working beutifully so its on to my next task...cars only blowing cold air..icarsofts telling me I have 3 faults but doesn't tell what they are? Maybe time to get a proper diagnostic so recommendations welcome Anyhoo clear the faults but they keep coming back and its frustrating not knowing what they are...any help is welcomed and I'm actually looking forward to solving another problem ..

Ours did that just before the head gasket blew- it was air circulating/locked in the heater matrix that meant no coolant was circulating to heat the air. Check the coolant system is bled properly.

Just been reading about it..looks straight forward enough to bleed..cheers

Tims 7 series guide to bleeding in meeknet- maybe a google to find it- is really good.

An airlock would not be registered as a fault, if you have an airlock you will know about it soon enough as the pressure the system works at will soon get it out the system via the overflow cap release valve...

The IID is the prefered tool for all faults, it is pricey but it does more than JLR can with your vehicle and the back up and support is first rate....  Pete
I now have permission from the boss to use Y.O.L.O. Enjoy life

@ huntsman cheers will check it out and try to bleed it as a maintenance job..

@haylands that's the one I've been looking at as I've seen it mentioned in here a lot.I should have bought it first...defo need it as my current diagnostic (icarsoft) is limited in what it can do.planning on having a l322 for a while so its going to pay for itself...where did you get yours? Thanks for input

Appears to have been air in the system..did a bleed and heatings now piping! still needing to investigate the 3 faults that are showing..iid tool is getting purchased this month! Early Xmas pressie I think.. Thanks gents!

Nice! Keep an eye on the coolant level - I'm replacing all of my pipes tomorrow- they're all old n' leaky

Dan at Duckworth (site sponsor on here) usually has the best price for the IID tool.
